Tom Silva lends some support to a homeowner suffering under a rotted porch post. Tom and the homeowner dig into the rotten post base to find the issue, and then get to work removing the affected wood. Next, Tom shows the homeowner how to mill new components from a recycled, water-resistant material before putting everything back together for caulk and paint.

How To Repair Rotted Porch Post
1. Place the 4x4 post and bottle jack underneath a header on the porch and lift the porch roof slightly until the post is free from the ground. Remove any of the rotted material by hand, but do not reach under the post for safety’s sake.
2. Use a reciprocating saw fitted with a 10-inch wood cutting blade to remove the rot. Be sure to make this cut as level and evenly as possible.
3. Cut a piece of the rice hull board or wood to the correct square dimensions. Often, this is 2 or 3 inches wider than the post’s diameter. It might be necessary to double this block with an additional layer of wood to match the other posts. If that’s the case, glue the two blocks together with a fast-setting adhesive.
4. Place the block under the post and level it side to side and front to back with shims. Once level, place small strips of wood along the perimeter on top of the block. Use the scribes to mark the pitch of the surface on these strips. Be sure to mark each strip and its location as you go. Cut the strips along the scribe lines on a bandsaw or table saw before gluing them to the block with the adhesive.
5. Use the scribes to draw a circle of the appropriate size on a piece of the rice hull board or wood. For thicker profiles, screw two layers of the wood together before cutting along the circle with the jigsaw. Sand both layers smooth and evenly, and add a detail with a router, if desired.
6. Repeat the last step, but with a smaller circle to create a cascading profile. Drill a ¾-inch hole in the middle of each of these circles to allow for airflow and prevent future rot.
7. Assemble the pieces under the post. Before lowering the post, squeeze a bead of construction adhesive between the post and the new base.
8. Lower the jack slowly, allowing the post to settle on the base and squeeze the excess construction adhesive out. Smooth the excess adhesive before allowing it to dry.
9. At each corner, drive a screw from the top-most layer of the base into the bottom base. Fill the screw holes and paint.

Man I wish I could sit down with Tom Silva and just pick his mind. Guy is an Encyclopedia of woodworking.
Same. However i can't forgive him for securing loose floorb by driving screws through the carpet
@@ryk3899 Link?
@Eric K find it yourself
@@ryk3899 I've had good results doing that using O'Beery's Squeak No More products. Worked well thru carpet and bare floor.
@@ryk3899 Did he use the screws that are designed to do exactly what you described? Because if so, then he did it exactly correct...
The guy raking leaves in the background was the real star.
Did you just assume its gender

I've been a fan for 38 years..I never get tired watching ..
Tommy is such a wealth of knowledge. The handyman business is growing due to guys like Sam and there’s lots of them out there.
I Make My Living Off Sam's!!!
The Problem Is Society Valves The Sam's More Than The Tom's!!!
Love it when I get a video from this old house featuring Tommy or Nathan
Love watching Tommy. Such an unbelievable craftsman
Tom making the dude do vacuum cleaner duty when he CLEARLY had a dust port is a boss move lol
That's why TOH has been favorite home improvement tv show since great projects like this porch column base repair & other helpful tips from the pros. Tom, Richard,Norm,Nathan & new member Jenn
Tommy is the man, he can fix anything!
Tom Silva is a master of all trades. He's a joiner, carpenter, cabinetmaker, woodworker, framer, etc.
Love the show the magazine and the RUclips videos. I have learned a great deal watching for decade’s. Thanks
A true professional vacuum cleaner operator here! 5:15 ......🤣🤣🤣
Yes, he sucks at sucking. Also, why vacuum outdoors?
I need to replace the 4 2x4 posts inside my front porch column and seeing this video made it look easy
Always pleasure watching Tom work...:)
I hope they did the other side as well. Eventually the other side will go, why not cut identical pieces and just do both since it's so easy!
Ask This Old House always does this. I think the idea is the homeowner has now learned what they need to do, and will tackle the rest of it themselves.
... for all we know, they did do the other side, but it's not shown in this shortened clip.
Sammy Pockets did a great job supervising.
I could watch Tommy for hours
I love this program I grew up watching it
Excelente trabajo. Me fascinó.
Gracias 🙏🙏💯
I think this technique is going to work to repair 4-5 column bases at my brother and sister-in-law’s.
Was the base anchored to the concrete?
So happy to see some fresh content
Great work... But I fear that a considerable wind will rip the porch roof off because the column is not secured to the foundation!
Mine are not secured and never have been, house built in 1880. The weight of the roof should keep them in place ... barring an insane wind.
Notice his are secure at the top so any minor roof lift by wind will keep it in place.
Dude just has his hands in his pockets the whole time....thanks for helping bro
Lol
🤣
But that vacuum action at 5:15 was something else
There are some, that's the most you can expect.
?? No more than any other person they’ve had on the show
Tom is the man!
Primer on the bottom of the old wooden Column would help
Oh Tommy!
Awesome Project!
Tommy always makes it look so simple.
How did he cut the bottom boards that he scribed though?
I noticed they left that part out too...a bandsaw would be a good tool for cutting the scribes, but on the jobsite perhaps a jigsaw would work moderately, if you can brace the scribe somehow.
I know for the broadcast TV show there are time constraints. But it's time that you make an online version that shows the full details. I can't believe they spent this much time showing how they leveled it and put those scribe pieces on the bottom but then never showed how to actually cut to the scribe marks
I came to the comments looking for that same explanation. They look too thin for a table saw. Maybe they used a bench sander?
Came out great. Would adding a plastic liner in between the post and the concrete be a bad idea? Since water makes its way from the concrete up into the post.
2:39
The materials they used do not absorb moisture as it is made with the hulls of rice and polymer for adding a bit of strength. There would be little benefit to plastic.
This product is called Resysta.
Still should of put a two light coats of Rubberseal or Kilz on the bottom of base just to be on the safe side.
@@kalijasin no
@@kalijasin Should HAVE , not should of....
great video . thank you for this.
This is identical to my house outside Boston.
Look at Tommy wearing Patagucci😂
Forgot to show how he made those pieces level after he scribed them
Love this video but Sir, where are your GLOVES?
Thought this was NS Builders for a second lol
Thought that also, both on thumbnail and for a split second at the door.
“Nice and tight”…Tom Silva
Ecelente jobs! USA
Me gusta mucho sus trabajos
i have some somewhat square posts sitting on concrete columns with stone accents that have trim going around them that keep rotting and needing to be replaced every so often , what can i do to prevent that ? i understand that they absorb the moisture from the stone column.
I've got some kind of metal base at the bottom of the only portch columb I have, but the wood around it is starting to rot. I can fix it myself if I knew what all it wil take to replace it
Did you buy the rice hull board by the sheet or by the trim board?
What did you remove the material with on the scribed pieces?
They used a jigsaw or a sabresaw.
@@Farm_fab Thanks, I didn’t see it..lol.
I had to rewind to see if I somehow missed it, but yeah odd to leave that out.
Nailed it.🤣🤣🤣🤣
Should they tapcon that base to the porch? The screws he sunk into it looked like they wouldn't reach the cement porch. Maybe it was just the angle?
Plz make video om how to repair old normal door. Specially washroom door that has holes..
Is this material at the base okay to support a heavy duty roof?
What’s the board called?
can anyone suggest other material options that rice hull board? It's hard to find. Thanks
You've come this far, probably should've inspected and reworked the column too.
They started out with the inspection on that column right at the beginning of the video
@@Engineer9736 Poking a Leatherman at a column doesn't mean the inside is sound. Look at the carpenter ant nest that came out of there.
@@paulmitrano3612 the rot starts from the outside inward, and the rot made it easy for the ants to cause damage.
A hole was drilled in the center of the new post base so air could go up into the column to keep it dry. But how is air going to get though if the joints are sealed? I have to fix my front porch corner column and porch because the previous owners didn't clean out the gutter, so the water overflowed onto the porch & column.
You can put spacers under the base to allow moisture release.
I’m confused! Was the column hollow or did the ants eat into the column? That nest came down as soon as he cut the post!
The ants moved the wood from below, up into the column. Most columns are hollow. Tapered or non-tapered fluted or plain are all hollow. Also when you look at the different materials: polymer stone, fiberglass, PVC and even wood they are all hollow. ... A wood porch column is made by gluing staves together in a circular form and then turning and cutting them on a lathe.
@@tj_gsomething_ So … the concern is whether the carpenter ants continued to eat their way up the post. It looks like the infestation is not still active.
The column is hollow. The nest was likely sitting right on top.
... basically, the ants stop where the water problem stops. Worst case is they cut the column higher and make a taller base, then match it on the other side.
Does anyone know if these columns are load bearing ? They are hollow . My house has the exact same columns and structures .
Yes, they are. That's why the bottle jack was used to take the load off the column while the repair was being done.
I have the exact same problem, but can’t find the same type of lumber. Does anyone know where to find it?
Darn it, he didn't say "rabbet" or "dado." It's not really a Tom Silva video unless at least one of those words comes up.
How about temba.
@@jacobtracy7847 ... Tom is good but Norm would have made several pieces then used his biscuit cutter to glue things up, PLUS, doing several passes with the router blades to make a decorative bead accent for each layer.
How much would y’all charge for this job
if Sam is looking for his hands,there in his pockets.
Why not to change both of bases, for a longer life?
Isn't the column still weak and hallow from the center . When tommy took the old one out , alot of bad wood came out ?
That was the ant nest. It would appear that the center of the columns is hollow.
👍👍👍👍👍👍👍👍
Why didn’t you anchor the post into the concrete?
Do I need (stair) sub-treads to go under 1inch solid oak stair treads? I removed carpet off the steps, currently there are 2 inch raw construction treads. I will take those off and replace with 1 inch solid oak treads. But I will loose 1 inch rise. I have 3 stringers, left right and middle. Thanks.
Glue 2 1x together and router. Or use 2x oak or whatever you want again.
Good chance the base rotted because that bush was overgrown for many years. No bushes on the other side = no moisture and no rot.
Maybe spray some insecticide up inside the hollowed out column before reassembling? I think those ants will continue to eat up the column.
I wonder what the bottom of the column looked like. Too bad the camera cut away and didn’t show it.
@@MoneyManHolmes Seemed bug-hollowed when the nest material fell out, which is what prompted my suggestion. I'd say you saw what I saw... :)
Does jacking it up not damage the house or loosen any nails or screws?
No, not at all. Very common practice. You're only jacking it up less than an inch.
@@mae2759 ... in most cases it's less than 1/8 inch. At that height you are not pulling nails or screws. You are basically flexing the wood. (no more than what happens with a change of season)
where did he put the jack?
Back in the truck when he was done.
I know it's a budget difference, but wouldn't a better long-term solution be replacing the columns with fiberglass columns?
Fiberglass will definitely last longer than wood. So yes it's gotta be a budget difference. They didn't even recommend doing the other side. You know that other side will need updating soon!
@@tj_gsomething_ they may have done this this way so the homeowner could do this at some point in the future, and teach him some responsibility.
I am not an expert on this, but should I worry about the hollow center of the square base? the square base is glued from 2 pieces and supported only on the 4 sides, while the center of the base supports the weight of the column and the porch, am I worrying too much?
The column is round and hollow, so the weight is actually on the edges of the square base, not center. ⭕🔲
You never place wood directly on a concrete porch. The wood will act like a sponge with any moisture that may be sitting on concrete. Get a specific either metal or reinforced plastic base to separate contact between concrete and wood
Agreed. I would have done what you said but my porch is wood.
I don't think he's going to paint it, his hands in his pockets say it all
He was playing "pocket pool" while admiring Tom Silva work that column 🎱
The Show should have brought pocket-less trousers for the home-owner.
Who would I call to have porch columns installed?
Ghostbusters
“Copenter” ants 🐜
hope that homeowner didn't stretch out those kaki pant pockets too much.
A little kilz primer and your good for a few years.
Does the homeowner ever take his hands out of his pockets?
I thought the idea of this show was for the home owner to help Tommy.Hard to do that with your hands in your pockets.
I have a question for this old house……
I have a120 year old house. During a remodel they reframed the stairs. Now they lean. How do I fix that? I can send pics.
Is the foundation sinking/settling? If you place a ball on the floor, does it roll in the same direction? Maybe the house needs to be leveled?
You tell the guy you paid for the remodel to come back and fix it.

Ours are concrete and about 25" square..I hope they don't rot 🤭
Carpenter ants 🙈

Wow he actually used a mdf type material and no damp proof protection
2:50 First watch the video before barking
@@Engineer9736 they used a product called Resysta that's made from polymer and rice hulls, and is impervious to moisture.
Mdf lol...
@@Farm_fab They explained that, yes, you have to say that to Fire Blaster, he didn’t hear it
This video is how to REPAIR a porch column...not REPLACING one!!
It would help if folks would put proper titles on their videos!!
A helpful video for repairing them, but it gets a thumbs down b/c it's not doing what the title says its supposed to be doing!
